You do not have to wipe, but its always recommended, so if you have a problem, wipe it

Instructions…

1. Download the FRF84B-Released.zip file to your SD card.
2. Open ROM Manager and choose “Install ROM from SD card.”
3. Navigate to the location you just downloaded the file to.
4. Tap on the file.
5. Check the box to create a backup in case something happens with the install.
6. No need to wipe data and cache if coming from another Froyo ROM.
7. Allow your phone to boot into recovery and work some magic.
8. First reboot could take a while so be patient.
9. Enjoy!
